Normally you would plug this in before turning it on, the right side has the main motherboard connector.\u00a0 \u00a0 Note on the left side there is a smaller connector, if you do not connect the left side, the 12V2 rail will blink L.L and you will have a warning beep sound.<\/p>\n
The others give off the 5V 3.3V and 12V, this coolmaster power supply is showing slightly less than 12V and slightly more than 5V.<\/p>\n
The 280ms PG measures how long before the power supply sends a “Power Good” signal to the motherboard, it should be between 100 and 500ms<\/p>\n
The bottom port (which you can barely see in this picture) measure the old school HD power molex and the 12v and 5v LED on the left should turn on.<\/p>\n
The top port (which you cannot see) measures a SATA power connector and should light up all three 12V 3.3V and 5V.<\/p>\n
The left also has a floppy power connector and it too should only have 12V and 5V.<\/p>\n
Finally on the left if you remove the 2nd 12V rail connector, you can test PCI-E power connectors.<\/p>\n
Kind of cool, pain that there is not much documentation, but a little web research told me what I needed.\u00a0 Of course if I really wanted to test this I would test it on an o-scope.<\/p>\n
Here are some external links that helped<\/p>\n
